This Stochastic indicator can be applied to any timeframe, higher or lower than the current chart's timeframe.

You can use all the usual parameters of the built-in iStochastic indicator, the only extra setting is the second timeframe used as input for the calculations.

When the indicator is applied to a timeframe lower than the current chart's time frame it's not possible to display all values. In this case, depending on the price type chosen, it will use a different approach to give the most appropriate value.

Two examples:

timeframe_1=5 minutes, timeframe_2=1 minute, calculations based on Close price series:

For any bar on timeframe_1, the indicator will show the latest bar of timeframe_2 with a Close time before or at the Close time of the bar at timeframe_1. This goes for bars that have been closed as well as the current bar that's still open.

timeframe_1=5 minutes, timeframe_2=1 minute, calculations based on Open price series:

For any bar at timeframe_1, the indicator will show the latest bar of timeframe_2 with a opening time before or at the Open time of the bar on timeframe_1. This goes for bars that have been closed as well as the current bar that's still open. The logic here is that if you choose to calculate your indicators on the Open time of a bar then probably you will also trade when a new bar opens. In that case, at the Open of a new
5-minute bar, you will only know the Open of the first of the five 1-minute bars that are part of it. The Open of the second to fifth 1-minute bars are therefore ignored in the calculations.

You can mix any time frame with any other time frame, even if they are not in sync, e.g. timeframe_1 = 5 minutes and timeframe_2 = 12 minutes. The indicator will make sure they stay synced. The way this works is similar to the examples above.
